To all whom it may concern:

Be it known that I, -WILL1AM E. FOWLER, J r. a citizen of the UnitedStates, residing at Hammond, in the county of Lake and State of Indiana,have invented certain new, and useful Improvements in Brake-Heads, ofwhich the'followin is a specification.

My invention, winch pertains to railwaycar brake-beams, has for its mainand princi palpurposethe provision of a brake-beam with brake-headswhich willbe securely held thereon from movement lengthwise of the beam,and which may readily be adjusted angularly thereon, and maintained inadjusted position by a simple and effective locking means. In thepreferred and most desirable embodiment of the invention, each end ofthe beam has a sleeve externally grooved transversely, the groove havingone or more open mouths or entrances for the admission of a lug orprojection on the inner surface of the brake-head hub, this projectionand groove forming a bayonet joint and preventing dis-' placement of thehead longitudinally on the cam. The bottom of the groove is preferablyroughened, and co-acting with such surface I provide a locking blockmounted in a recess or pocket in the brake-head, and actuated or pressedinto locking engagement with the sleeve by a slidable wedge," in therecess 2 back of the lock-block, this wedge having an a ertureaccommodating the head of a bolt, t e other end of which is extendedoutwardly through a hole in the brake-beam head, and being equipped witha nut adapted to actuate the wedge and force the lock-block against theroughened surface of the sleeve to hold the head in adjusted angularposition.

A desirable embodiment of this invention is illustrated on theaccompanying drawing forming a part of this s ecification, and to whichreference should e made in connection with the following detaildescription.

On the drawings,Figure 1 is a substantially central-vertical sectionthrough the brake-head and sleeve forming a art of the brake-beam Fig. 2is a section on no 22 of Fig. 1 as viewed in the direction indicated by.

the arrows; Fig. 3 is a top plan view of the brake-beam sleeve; andFigs. 4 and 5 are fragmentary sections illustrating the manner ofpositioning the lockin block and wedge in the pocket or recess of t ebrake-head.

Refe'rringto the drawings, itwill be noted that the brake beam has acompression bar' 10 and a tension rod 11, on the ends of which is fitteda sleeve 12 having the customary and usual flange 13 at one end, andalso having on its exterior surface a curved groove or slot 14withright-angle extensions 15 and 16 at its opposite ends and leading to theends of the sleeve, as is clearly indicated in the figures. The bottomof this groove 14 on the top and bottom of the sleeve is serrated ortoothed or roughened at 17 and 18, for a purpose hereinafter indicated.

The brake-head 19 is supplied in its lower portion with a pocket orrecess 20 having a curved entrance or mouth 21 somewhat narrower thanthe full width of the pocket. My improved locking means includes alockblock 22 having a concave roughened or serrated surface "23 on oneside, the o posite surface of the block being inclined or eveled at 24.This block, as is clearly shown in the drawings, is adapted tofit in themouth of the recess or pocket and extend out of the faces of the blockand the bottom of the groove co-acting as will be readily understood.Also in this'pocket or recess 20 I provide a sliding wedge 25, theinclined surface of which bears a ainst the corresponding surface 24 ofthe lock-block, while its opposite face rests upon and is adapted toslide upon under face this wedge 25 has an undercut recess or cavity '26adapted to accommodate and receive the head 27 and a portion of theshank of a bolt 28, the cooperation of the parts being shown in. Figs.1, 2 and 4. The side walls of the pocket or recess 20 are apereither oneof which holes the shank of bolt 28 is adapted to be passed, a nut 31 onthe end of the bolt being used to draw the wedge o'r inclined surfacesof the wedge-block 25 and the lock-block 22 together toforce thelock-block intofirm engagement with the roughened surface of thesleeve.' A nut-lock be em loyed' to co-act with the nut and the brakeeadto prevent loosening or unturning of theformer.

The interior cylindrical surface 33 of the hub34 of the-brake-head issupplied with an inwardly extended projection or lug 35 adapted tp'fitin the groove 14 and prevent lengthwise or longitudinal shifting of thehead on-the sleeve 'or beam, this lug 35 when same into the groove 14,the roughened surthe bottom of the recess or pocket. On its tured orperforated at 29 and 30, through 32 of any usual and ordinary charactermay the head is being placed on the beam passing,

into the slot 14 through one or the other entrances or mouths 15 or 16.In some cases it may not be necessary to use this projection or lug 35,but in the preferred form of my device I employ such a construction, andhave therefore illustrated the same on the drawings; and when such a lugis'.not used reliance is placed solely upon the lock-block 22 to prevent'longitudina movement of the head on the beam.

The parts of thisdevice are assembled in a manner substantially asfollows: The bolt 28 having been placed in the recess or pocket 20 withone end extended out through one or the other holes 29 0r 30, thewedge-block is introduced into the pocket through the entrance ormouth21, the bolt being so held in place that as the. wedge-block drops intothe pocket the bolt-head 27 will be received in the undercut portion ofthe recess 26. The wedge and block are then pushed to one side, as isindicated in Fig. 4, and the lock-block 22 introduced into the pocketthrough the mouth 21, the

such as to allow t 1e lock-block to drop into the 5 pocket sufficientlyto permit the brake-head 1 ob to he slid lengthwise on to the sleeve 12.ll hen belng placed on this sleeve the brakehead is turned around so asto permitthe inwardly extended finger or projection 35' to' enter theslot 14 through one of the mouths or entrances 15 or 16,-and after thisprojection 35 has entered the slot 1-1 the brake-head may be turnedangularly on the sleeve and brake-beam. to proper position, after whichthe nut 31 is screwed on the threaded portion of the bolt 28 so as todraw up the wedge 25, the latter by cooperation with the lockblock 22projecting the latter into the groove 14 until the roughened surfaces atthe bottom of the groove and on the concave face of the lock-block comeinto firm ei'igag'ement and act to hold the brake-head iii adjustedangular position. 'lli'l'ien this position of the parts has beensecured, the nut lock is ent up so as to prevent unturning or loosenm%of the nut.

f desired, the lock-block 22 may fit somewhat loosely in the pocket, sothat if the corrugations or serrations of the cooperating ing wedge.

The kind of sleeve illustrated on the draw ings is adapted for use ateither end of the -brake-beam, and for that reason the slot 1 1 ispreferably provided with two entrances eeoeea or mouths 1.5 and 16,either of which may be employed for admitting the projection 35 into thegroove. .Whereas but one roughened surface is indicated as being in usein Fig. l; the upper or inoperative serrated surface would be employedfor retaining the head in place if the sleeve were used at the oppositeend of the brake-bcam.

' It is to be understood that this invention is not limited andrestricted to the precise construction shown and described, because theminor mechanical features thereof may be modified within \vidc limitswithoutdeparture from the scope and essence of this invention.
